The test was done with the following GStreamer pipeline: $ gst-launch-1.0 videotestsrc num-buffers=20 ! video/x-raw,format=UYVY \ ! v4l2video3convert ! video/x-raw,format=xRGB ! videoconvert ! kmssink The manual seems to state that the Pixel Format are in Little Endianness so instead use the 32-bit BGRA/X 8-8-8-8 pixel format. This format works correctly when using the following pipeline: $ gst-launch-1.0 videotestsrc num-buffers=20 ! video/x-raw,format=UYVY \ ! v4l2video3convert ! video/x-raw,format=BGRx ! kmssink This change is similar to commit 7f2816e51ea1 ("[media] s5p-fimc: Changed RGB32 to BGR32") that fixed the same issue on a different Samsung driver.
